I MACHINE FOR MAKING VIALS AND THE LIKE Specification of Letters Patent. Application filed January 4, 1910, Serial No. 536,286. Renewed October Patented Apr. as, rare.

18, 1911. Serial No. 655,419.

To all whom it may concern:

Be it known that I, WILLIAM R. BUR- ROWS, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful improvements in Machines for Making Vials and the Like, of which the following is a specification.

The invention relates to the manufacture of small glass vials or bottles more particularly of the character used for holding homeopathic medicines, and it consists in the novel machine, features, cooperative mechanisms and method hereinafter described and claimed. e

In accordancewith my invention the vials are completely made by automatic mechanism from a tube of glass, the tube being of any appropriate initial length and the vials, one after another, being made and severed from the end thereof.

One of the main objects of my invention is to enable the correct and rapid automatic manufacture of the vials, one after another, rom the advance end of a glass tube or the advance ends of glass tubes, when more than one tube is handled by the machine. I prefer to so construct the machine that at least two tubes may be fedthereto and vials made om the advance ends thereof by substantially the same set of mechanisms that would be employed if only one tube were fed to and handled by the machine.

he machine of my invention comprises, in the preferred embodiment, a vertical inframe having horizontal arms provided on their ends with chucks for holding, vertically, the glass tubes from whose lower or advance ends the bottles or vials are made and through which chucks the tubes are fed as the vials are in succession formed from the lower ends thereof, means for forming the lip, neck and the lower end of each shoulder for a vial on tube as the same is carried by said frame thereto, and means for severing. by flameof each tube carried to the proper position for this step by said frame, said flame-jets while severing the ower section of the tube from the body section andthe lower adjacent end of the body of the tube. The severed section of the tube constitutes an inverted vial and is received in a clampframe and carried therean air-suction nozzle by first to means for flattening the upper end thereof and then to a position at which seizes the vial at its closed end and withdraws the same from said clamp-frame and delivers it to any suitable means placed to receive the finished vials, as, for instance, to a chute down which the vials may slide to a conveniently placed box or receptacle.

he means for flattening the closed end of 5 the inverted vial preferably consists of a patter or flat plate lightly applied to the exterior of said end and means for driving air under suitable pressure into the open end of the vialfor forcing upwardly any depressed portion of said closed end against the fiat lower face of said plate.

The machine also comprises means for preparing the lower closed end of the body of the glass tube from which the section for the vial was severed, for the formation thereat of the lip, neck and shoulder of the next vial to be made, and these means comprise, first, a suction nozzle to which the rotary frame carries the tube and which, by air-suction, draws downwardly in the form of an annular open thin flange the still hot glass which closed the lower end of the tube, and, secondly, a former-plug to which the rotary frame then carries the tube and which, in the presence of heating flames, shapes the lower end of the tube and moves the said flange upwardly or back into the body of the tube, whereby the lower end of the tube is given proper thickness, shape and body to enable the formation thereat of the lip, neck and shoulder for the next vial to be made. The tube is then carried by said rotary frame to the means above referred to for forming the lip, neck and shoulder on the lower end of the tube and then to the position at which the lower section of the tube is severed from the body thereof to constitute an inverted vial, which, as described, is received by a' clamp-frame and by it carried first to means for flattening the closed end of the vial and then to a position at which the suction-nozzle extracts the finished vial from said clamp frame and delivers it to a suitable discharge.

The invention will be fully understood from the detailed descri tion hereinafter presented, reference being had tothe accompanying drawings, in which:

In the drawings 50 designates the bedplate of the machine, '51 a belt-wheel, 52 a driven shaft located below the bed-plate 50. 53 a driving shaft mounted in bearings 54 at the rear of the machine, and 55 a camshaft supported in suitable bearings over said bed-plate. Power is communicated from the shaft 52 through a sprocket chain 56 to the shaft 53 and thence through a sprocket chain 57 to the shaft 55. A clutch 58 is provided for the shaft and a clutch 59 for the shaft i The rotary frame which carries the glass tubes from which the bottles are made is more clearly illustrated in Figs. 1, 2 and 13, and the gearing by which said frame is given an intermittent motion is illustrated in Figs. 2, 12 and 13. The rotary frame as a whole is designated by the numeral 60 (Figs. '2-

and 13), and it is mounted in a vertical hearing frame. 61 secured to the bed-plate 56.

The frame 60 comprises a tubular shaft 62 having secured to its upper end a horizontal bar 63 at whose center is a hub to pass upon the upper end of the tube 62, as shown in Fig. 13. At the outer end of each arm of the bar 63 is provided a chuck 6-1 for holding and manipulating a glass tube- 65. The

chucks 64 correspond in construction with ball-bearings, as shown at the left hand side of Fig. 13, to support said gear-whcel and its member 66 and enable the proper rotation of said gear-wheel and parts connected with it. \Vithin the tubular member 66 is provided a vertical slidable tubular member 69 which extends above the gear wheel 67 and through which passes the glass tube 65. The

lower end of the member 69 has several jaws,

preferably three, 70 connected to it by links 71; The inner surfaces of the jawsTO are smooth and adapted to evenly engage the surface of the glass tube 65, while the outer surfaces of said jaws are wedge-shaped and engage-the lower inwardly inclined edges of the chuckanember 66. are allowed to descend to their lower position, shown in Fig. 13, they become clamped against the tube and hold the same rigidly. When the tubular member 69 is elevated it draws the jaws 'upwardly from the inclined lower edges of the tubular member 66 and atsuch time said jaws release the tube 65 and the latter is left free to descend through the chuck. The chuck-member 69 is swiveled within an opening in a pivoted arm 72 carrying upon its outer end an adjustable member 73, in this instance a bolt, which. duringthe rotation of the frame 60 passes over a pivoted operating arm 7-1 (Figs. 1 and 3) provided for the purpose of turning the arm 72 upwardly to elevate the chuck-member 6t) and jaws 70, so that at such time the tube 65 may be free to descend. The point at which the tube 65 is released to descend is when said tube having had the lip, neck and shoulder or bottle-hcad formed on its lower end, is to be subjected at a-suitable distance above said lower end to the ac tion of the fiame-jets'for'severing from the tube an appropriate section thereof to constitute a vial.

The frame 60 has an intermittent rotary motion imparted to it and during some of its periods of rest the chucks 64 have rotary motion imparted to them. The means for imparting motion to a ohu- 2k 64 when in the position shown at the left hand side of Figs.

\Vhen the jaws 70 1 and 13, comprise a rod 75 extending up- 'wardly through the frame 60, a gear wheel with which the gear-wheel 67 of the chuck 64 is carried into mesh when the frame 60 rotates to move said chuck to the position shown in Figs. 1 and 13 with relation to said pinion-wheel. The pinion-wheel 77 is mounted on a pin 78 which extends through aplate 79 (Fig. 13) located below the gearwheel 7 6 and secured upon the upper end of a stationary tube 80 disposed within the outer tube 62 of the frame 60. The lower end of the pin 78 is connected by a light spring 81 with the plate 79 and said pin is secured in the opening in said plate by means of a transverse pivot, with the result that the pinion 77 may have a limited yielding movement sufficient to relieve any jarring or harshness of engagement which might otherwise take place when the frame 60 is turned to carry the gear wheel 67 of the chuck 6- into mesh with said pinion-wheel. The lower end of the stationary tube 80 is held by a screw in a bracket-arm 82 (Fig. 13) and cooperates with said arm in supporting the frame 60 vertically. The upper end of the rod 7 5, which passes through the frame 60, receives a block 83 to which the inner ends of the arms 7 2 are pivotally connected.

The means for rotating the frame .60 with an intermittent movement from the shaft 52 comprise (Figs. 2 and 12), a beveled gearwheel 84 on said shaft, a beveled gear-wheel 85 in mesh therewith and connected with a disk 86, and the slotted plate 87 secured by a' screw, as shown in Fig. 13, upon the lower end of the tube 62 upon whose upper end the cross-bar (S3 of the frame (50 is secured. The disk 86 and slotted plate 87 form a Geneva movement of known character. In the present instance the rotary frame 60 will have four periods of rest, and hence the plate 87 is formed with four slots 88 to receive the pin 89 carried by the disk 86 and said plate between said slots is recessed, as usual. to receive a peripheral portion of said disk.

The means for rotating the vertical rod 75 extending through the frame 60 and car rying at its upper end the gear-wheel .76, comprise a pulley-wheel 90 secured upon the lower end of said rod and a cord or belt 91 which extends over pulley-wheels 92 secured on the driving shaft 53. The rod 75, gear-wheel 76 and pinion 77 may continue in constant rotation, but said p'inion wheel being held in a fixed location is only able to perform its functions when the gear-wheel (37 ofa chuck 6-1 is moved into engagement with it.

I utilize the tubular member 62 of'the frame 60 and the rod 75 extending through motion imparted to it.

trated in Figs. 1 and 13, the left hand chuck 64 is in engagement with the pinion wheel 77, and, as hereinbefore indicated, the said chuck 64 is in such position during the period that the lower section of a glass tube having the vial head formed on its lower end, is being severed by the action of heat from the body of the tube. When the said left hand chuck 64, looking at Figs. 1 and 13, is by a quarter-turn of the frame 60 carried to the front or over the suction-nozzle 93, as shown in Fig. 2, said chuck will have no independent rotary movement, there being when said chuck is in such position no means provided for rotating the chuck and none being'necessary, since in that position of the chuck air suction through the'nozzle 93 is acting to pull downwardly and open the closed lower end of the tube. When the said chuck 64 is by a further quarter turn of the frame 60 carried from its position over the suction-nozzle'93, it will stand over the means provided for shaping and thickening up the lower end of the tube, saidmeans being shown in detail in Figs. 8 to 11 inclusive, and since at such time it is desirable that. the tube should be rotated, I provide the gear-wheel 94 with which at such position the gear-wheel 67 of the chuck passes into engagement. The gear-wheel 9% is driven from the cord or belt 95 which passes around a pulley-wheel 96 mounted on the spindle 97 (Figs. 4 and 5) supporting said gear-wheel 94:. The gear-wheel 94 is loose on the spindle 97 and carries on its upper face a friction-disk 98. The pulley-wheel 9G is secured to a disk or head 99 which engages the friction disk 98, and above the pulley-wheel 96 is provided a spring 100, which acts to press the head 99 against the disk 98. When the belt 95 and pulleywheel 96 are in motion and the head 99 is down against the.disk 98, the gear-wheel 9. will be rotated, and obviously when the pul- Icy-wheel 96 and head 99 are elevated from the disk 98, the gear wheel 94 will-not have Since during the movement of the rotary frame 60 the gear wheel 67 of the chuck is carried rather quickly into mesh with the gear-wheel 94, I provide means for 'momentarily elevating the head 99 from the disk 98 at the time the gear-=wheel 94; and these means are illustrated in Figs. 1 and 4 and comprise a pivoted lever'arm 101 whose upper end is arranged to engage a shoulder on the pulleywheel 96 and whose lower end is against a cam 102 on the shaft 55. During the rotation of the cam 102 a projection 103 thereon will ride against a roller carried by the lower er of the arm 101 and operate to rock said arm on its pivotal support and cause its upper end to lift the pulley-wheel and head 99 from the disk 98, and this happens at the moment it is intended the gearwheel 67 shall pass into mesh with the gearwheel 94. I also provide on the arm 101 a brake-arm 101 carrying. at its forward end a pad, which, when the arm 101 elevates the pulley-wheel 96, engages the lower surface of the gear-wheel 91 to lightly retard the movement of the same. As further relieving the gear-wheels 67, 94 from unnecessary jarring or harsh action when they come together, I pivotally mount the spindle 97, as shown in Figs. 4 and 5, and provide in the bracket-arm 105 an enlarged hole througli whichsaid spindle passes. I also connectto the spindle 97 a coiled spring 106 which tends to draw the shaft in a direction toward the adjacent chuck 6 1, but allows said spindleto yield in a direction from said chuck upon the gear wheel 67 of the latter striking the gear wheel 94. i

When the gear wheel 67 of the chuck is in mesh with the gear-wheel 94 and the pulley-wheel 96' has descended, the gear-wheel 91'will be rotated from the belt 95 and impart motion through the gear-wheel 67 to the'chuck,.with.the result that the latter and the glass tube carried by it will be rapidly rotated during the operation of the means for shaping, thickening and preparing the then ragged lower edge-of the glass tube. When the said chuck 64 is by the frame 60 given a further or its third quarter-movement on its cycle, it will be carried away from the gear-wheel 941 and into mesh with a similar gear-wheel 107 or to the position illustrated in Fig. 2, in which position of the chuck the means for forming the lip and neck on the end of the tube perform their duty. The gear-wheel'107 corresponds in its details with the gear-wheel 91 and its cotiperating parts just described in connection with Figs. 4 and 5, and hence but brief description is necessary with regard to the gear-wheel 107. The gear-wheel 107 has on its upper face a friction disk 108, which is engaged by ahead 109 connected with a pulley-wheel 110. Power is communicated to the pulley-wheel 110, head 109 and gearwheel 107 through a belt 111 clearly illustrated in Fig. 1. and a spring 112 is utilized to press the head 109downwardly against the disk'108. The gear-wheel 107 is supported on the upper portion of a pivoted. spindle 113 connected with a spring 114, which tends to yieldingly press the gear-wheel 107 in a di' rection toward the gear-wheel 67 of the chuck 64 it is to engage. When the gear tion and severance of a vial therefrom.

wheel of the chuck is about to pass into engagement with the gear-wheel 107 by which it is to be driven, the pulley-wheel 110 is elevated to free the head 109 from the friction disk 108, and the means for then elevating said. pulley-wheel and head comprise a lever-arm 115 (Fig. 2) secured on a rock-shaft 116 (Fig. 1) carrying an operating arm 117 and a brake-arm 118. The arm 117 has an angular member 119 below a pivoted arm 120 which has its free end below a shoulder on said pulley-wheel. When the arm 115 is turned toward the front it will cause the rock-shaft 116 to turn the arm 117 upwardly against the pivoted arm 120 to cause the latter to elevate the pulley-wheel 110, and at the same time the brake-arm 118 will apply moderate pressure against the lower face of the gear-wheel 107. The arm 115 is actuated by a cam 121 (Fig. 1) on the cam-shaft 55. \Vhen the said chuck 64 is *by the frame 60 given its fourth and final quarter movement of its cycle, it moves ,-.,l .i'ward the left from the gear wheel 107 and Qreti rns to its first described position at the left of the center of the frame 60, as shown in-Figs. .1 and 13, and its gear wheel 67 again passes into mesh with the transmitting pinion wheel 77, and it is at this stage that the outer end of the arm 7 2 above the chuck is elevated by the operating arm 74 and effects the release of the glass tube to descend to a sutiicient extent for the comple- The frame 60 may carry only one chuck 61 but the capacity of the machine may be increased by providing said frame with two chucks 67f. hen two chucks are made use of each follows the other through the cycle of four quarter-movements and the lower ends of the glass-tubes carried by them are successively subjected to the steps resulting in the formation of the vials.

Having described the construction and mode of operation of the rotary glass-tube carrying frame 60, with its chucks 64 and the means for rotating said chucks in their three positions in which their rotation is desired, I will proceed to describe the mechanisms which act against the lower portions of the tubes at the four atrest positions of said frame 60 to form the vials, and alsothc means which receive the severed vials and effect the flattening of their closed ends, as well as the means by which the completed vials are removed from the machine. In this portion of the description it will be convenient, since in starting the operation the lower end of the glass tube is open and of regular form, to consider that a chuck 64 when over the suction nozzle 93 (Fig. 2) received the tube andcarried it first to the at rest position of the frame 60 at which the gear wheel 67 of the chuck passed into.engagement with the operating gear wheel 94 and the lower end of the glass-tube while rotating was softened by the heat of flames from gas-burners 49, and then transported it to the rear position of said chuck at which its gear-wheel 67 engages theoperating gear wheel 107 and said chuck holds the glass tube 65 in position to have its softened lower end acted on by the means for forming the lip, neck and shoulder thereat, as shown in about the middle portion of Fig. 2. The means for at this time acting on the lower end of the rapidly rotating glass-tube 65 are shown enlarged in Figs. 14 and 15, and a gas-burner for constantly keeping the neckforming tools hot preparatory to this stage of the operation is shown in Fig. 1 and numbered 122. -The flame at the burner 122 is constant and the burner is not of unusual construction.

The tools for forming the lip, neck and shoulder on the lower end of the glass-tube 65 are two corresponding formers 123 adjustably secured by screws to the upper arms of corresponding bell-crank levers 124 and a plug 125 adapted to enter the lower open end of the tube. The bell-crank levers 124 are pivotally secured to a cross-bar 126 and are connected by links 127 with a block 128 which is connected with the upper end of a vertical rod 129, whose lower portion extends through ears 130 of a bar 131 (Fig.

15) which is pivotally secured at its lower end to a rockable lever-arm 132; Upon the rod 129 is a spring 133 confined between a collar 134 and the upper ear 130 and normally acting to yieldingly hold the rod 129 and block 128 pressed upwardly to the extent permitted by a stop 135 provided on the rod 129 below the lower ear 130. The normal idle position of the formers 123 is illustrated in Fig. 14, and at the time the formers are to engage the lower end of the glass tube 65', the outer end of the lever arm 132 is acted on by the cam 136 to move the rod 129 'upwardly and thereby through the bell-crank levers 124 cause the formers 123 to approach each other and engage opposite sides-of the end of the tube 65. The plug 125 is upon the upper end of a bar or head 137, which may rest upon the block 128 when in its lower position and is secured 141, the latter being on the rod, with the inner end of a pivoted lever 142. The rear end of the lever 142 is normally held upwardly by means of a coiled spring 143 and is intended to be turned downwardly when the plug 125 is to be elevated, by means of a suitable cam 144. Upon the rod 138, ,between the collar 141 anda collar 145, is provided the coiled spring 146, which, when the rod 138 is elevated, becomes compressed by the contact of the collar 145 with the lower end of the bearing 139 and affords a yielding resistance to the upward movement of the rod 138 and plug 125, it being desired that the plug 125 should not enter or act against the soft glass of thetube 65 with undue .harshness. The spring 146 cushions the thrust of the plug 125. The plug 125 is shown in its normal lower position and the formers 123 are shown in their normal idle position in Fig. 14,-while in Fig. 2 I illustrate said plug in its upper po sition and said formers in their inner operative position engaged in forming the lip and neck at the lower end of the glass tube 65. After the rotary frame 60-has remained a suflicient length of time holding the glass tube 65 for the action of the formers 123 and plug 125, said frame will carry the tube with the lip and neck formed thereon to the first described position for the chuck 64 or that indicated at the left hand portion of Fig. 1, upon arriving at which position the screw 73 on the arm 72 above the chuck will pass over the arm 74 and be by said arm, when the chuck has reached its definite position, moved upwardly so as to elevate the chuck member 69 and jaws to release the glass tube 65, whereupon said tube will descend to a clamp frame which I will presently describe, said tube then attaining the position illustrated in Fig. 17.

The arm 74, by, which the chuck 64 is caused to release the glass tube so that it may descend for the severing operation indicated in Fig. 17, is illustrated more clearly in'Figs. 1 and 3, and is pivotally supported on the upper end of a standard 147 and connected at its rear end by a link 148 with the upper horizontal arm of a bell-crank lever 149, whose other arm, indicated by dotted tion of the cam 150 rides against the vertical 1 arm of the bell-crank lever 149 it will cause the rear end of the pivoted arm 74 to move downwardly and the front end of said arm to move upwardly, with the result that the front end of the arm 74 will elevate the arm 72 of the chuck 64 and release the glass tube to descend to the clamp frame intended to receive it and at the time directly below the chuck 64 The clamp frame which receives the lower end of the glass tube when the latter.

descends through the chuck is duplicated in the present machine, and I number the two frames, which are just alike, 152, 153, and

said frames are mounted upon the outer place.v The arm 154 therefore is swiveledand carries two corresponding'frames 152, 153 each of which'upon receiving the lower end of the glass tube -remains stationary, except for having a rotary motion, until the bottle has been severed, and then moves on through the line of a quarter circle (to the rear and left looking at Fig. 1) to the position at which the flattening of the closed end of the bottletakes place. Each frame 152, 153 comprlses a cross-bar 155 secured upon the upper end of a sleeve 156 (Fig. 25), vertical rods 157 secured to the ends of the bar 155, and a slidable frame mounted on said rods 157 and comprising a cross-bar 158 and tubular rods 159, which are upon the rods 157 and adapted to have a vertical movement thereon. The upper ends of the tubular members 159 are connected by a bar 160 which afford horizontal guides for clamping members 161, 162 (Fig. 28). The clamping members 161, 162 are recessed at their facing edges to engage the glass tube when the same descends into the clamping frame, said members 161, 162 being in their separated position at the time the tube de scends. The clamping members or jaws 161, 162 have depending arms 163, which are connected by links 164 with the upper arms of corresponding bell crank levers 165 whose lower arms are at their outer ends connected by links 166 with a head 167 which is Vertically movableupon a central tubular rod 168 and yieldingly pressed upon by a coiled spring169. The tubular rod or shaft 168 extends vertically through the sleeve 156, cross-head 167, spring 169 and cross bar 158, and is vertically movable with the upper frame comprising the cross-bars 158, 160 and tubular rods 159. The frame 152 is also provided with a plate 17 0 having a vertical slot therein to receive the screw 171 by which said plate is 'adjustably fastened to the cross-bar 158. The upper end of the plate 170 turns inward horizontally, as at 172 (Figs. 25, 27), and contains an opening directly above the opening through the tubular shaft 168. Upon the upper bent end 17 2 of the plate 170 is provided a pad 173 upon which the descending glass tube will fall when released by its chuck to descend, and said pad has an opening in line with the opening in the upper bent end of said plate 170. When the frame 152 is attaining its position below the chuck 64 to receive the glass tube, the lower end of the tubular shaft 168 rides up an incline or cam 174 (Fig. 17) and passes over upon an adjustable rest 175 carried by a small bracket secured to the inner end of a pivoted lever arm 176, whose outer end is in engagement with a cam 177, which cam, when the parts are in the position shown in Fig. 17, maintain the tubular shaft 168 in its upper position a sufficient length 'of time for the descending glass tube to pass between the then separated clamping jaws 161, 162 and engage the seat 173 of the frame 152. When the tubular shaft 168 is moved upwardly it carries with it the cross-bars 158, 160, bellcrank levers 165 and links 166, moving said parts from their position shown in Fig. 25 to that illustrated in Fig.- 17 and causing the bar 160 to engage the collars 48 on-the upper ends of the rods 157. lVhen the bar 160 reaches the collars 48 it becomes arrested thereby but the shaft 168 continues its upward movement to a slight extent (compressing the spring 169) sufiicient to cause the links 166 and bell-crank-levers 165 to move the clamping jaws 161, 162 in a direction from each other or to their open position to receive the glass tube. After the tube has descended between the clamping jaws 161, 162 the cam 177 will turn its receding portions against the lever arm 176 and permit the tubular shaft 168 and parts carried thereby to settle downwardly to a suflicient extent to enable the clamping aws 161, 162, to -move toward each other and against the glass tube (Fig. 28). v

The frames 152, 153 while carried by the horizontal bar 154 are independently rotatable when said bar 154 is at rest. Upon the lower end of the sleeve 156 of each frame 152, 153 is secured a gear wheel 178 which will be carried intd engagement with gear wheels 179, 180 in succession, the gear wheel 178 of the frame 152 when performing the duty illustrated in Fig. 17, being in mesh with the gear wheel 179 (Fig. 3). After the stage of the operation on the bottle indicated in Fig. 17 has been completed and said frame 152 carries the substantially completed bottle to the position at which its closed end is flattened, the gear wheel 178 of said frame 152 will pass into engagementwith the gear wheel 180. The gear wheels 17$), 180 are driven from the gearing and belt mechanism shown in Fig. 12, and hence when the gear wheels 178 of the frame 152, 153 pass into engagement with said gear wheels 17 S), 180 said frames will be rapidly rotated, movement being coun'nunicated through the sleeve 156 to the cross-bar 155 and rods 157, and through said
